Question

The graph below shows a line segment AB.

Graph

Which of the following equations best represents the line segment AB?

y = -3x + 2

y = -2x + 1

y = -3x - 2

y = -2x - 1

Answer 1

thinking A or C!

Answer 2

@superdavesuper can you PPPPPPPPPPLLLLLLLLLLEEEEEEEAAAAAAAAAAAAASSSSSSSSSSSSSSEEEEEEEEEEE help?

Answer 3

@superdavesuper

Answer 4

okay

Answer 8

OK how are A and C different?

Answer 9

(I guess a lot)

Answer 10

Like I told u before, guessing do u very lil good :(

Answer 11

A is -3x + 2
and C is -3x -2

Answer 12

and I dont ask for the answers I just ask for the simplest way for yall to help me find it.

Answer 13

no, u didnt ask for ans so u are good on that :)
but u dont try to understand when i explain things to me n just start guessing n it makes me worry :(

Answer 14

ok now back to A and C....one said +2 and one said -2.....how can we find out which one is right?

Answer 15

Ummmmmmmmm...............plug in numbers????

Answer 16

Good idea!! hehehe first time i see u trying here :)

OK lets see what to plug in....do u see the vertical line in the middle where all the numbers 1,2,3,4,5 go?

Answer 17

:P and yeps

Answer 18

at that vertical line, x=0 okay?

Answer 19

okay.

Answer 20

So lets plug x=0 into
A is -3x + 2
and C is -3x -2
and see what happens?

Answer 21

okay so x is what? or is x were y goes bc in A and C it says y= -3x +2 and y= -3x +2

Answer 22

finding x? are we?

Answer 23

x=0

Answer 24

x=0
then -3x + 2=?

Answer 25

ooooooooooohhhhhhhhhhhh!!!!!!!!!!!!!!!!
-1?

Answer 26

no, x=0
then -3x + 2= -3(0) + 2 =?

Answer 27

or with - number does it go more - ?

Answer 28

WWWWAAAAAAAAAAIIIIIIIIIITTTTTTTTTT!!!!!! -3 time 0?

Answer 29

it is a 0 inside and everything that multiplies 0 will be 0 right?

Answer 30

yes, -3 times 0 indeed

Answer 31

and than 0 + 2?

Answer 32

U not reading my steps again :(

Answer 33

yes so x=0
then -3x + 2=?

Answer 34

2?

Answer 35

BECAUSE -3 times 0 is 0 and 0 + 2 it 2 :)

Answer 36

@superdavesuper

Answer 37

so u now get x=0, y=2 right?

Answer 38

yes!!!!!

Answer 39

now what?

Answer 40

READ this carefully!!!!

(x,y) means a POINT on the graph

u go to horizontal line in the middle and find x; then go vertical to y
that point is ur (x,y)

i cannot go on if u dont understand this

Answer 41

okay, and on this graph I think x is a and y is b so I got it, I think.
I kinda need to hurry because I have to leave in about 1 hour and I still have 4 questions left (after this)

Answer 42

what is the right ans for this?

Answer 43

(dont get mad if this isnt right) A?

Answer 44

Answer 45

YYYYYEEEEAAAAHHHH!!!!!

Answer 46

I am not mad...i AM worry about u thou. sorry I need to leave so good luck w the rest of ur assignments :)
